Converter with Short-Circuit Protection and
True Shutdown General Description Benefits and Features The MAX17227A is a nanoPower boost converter capable
of delivering load up to 2A peak inductor current and offering True Shutdown™, cycle-by-cycle inductor current limit, short-circuit, and thermal protection. During shutdown,
current drawn from the input pin is 1nA. The MAX17227A
offers ultra-low quiescent current, small total solution size,
and high efficiency throughout the load and line range.
The MAX17227A is ideal for battery-powered applications
where long battery life is a must and high efficiency is required at all power levels. ● 350nA Quiescent Supply Current from Output
● Output Short-Circuit Protection
● True Shutdown Mode
• 1nA Shutdown Current
• Output Disconnects from Input
• No Reverse-Current with Any Voltage on VOUT The MAX17227A utilizes adjustable on-time, pulse-frequency-modulation (PFM) control scheme that consumes
ultra-low quiescent current. The MAX17227A features
True Shutdown mode where the output disconnects from
the input with no forward or reverse-current. This saves
precious energy from the battery for systems that dynamically turn on and off by having the ability to startup into a
precharged output capacitor.
The MAX17227A is offered in a space-saving and costeffective 1.58mm x 0.89mm, 6-bump WLP (3 x 2, 0.4mm
pitch) and 8-pin, 2mm x 2mm TDFN packages. The operating temperature range is from -40°C to +125°C. Applications
